Final answer:
Secondary explosives are less sensitive than primary explosives, commonly used as the main charge, and designed to withstand handling.
Step-by-step explanation:
Secondary explosives constitute a class of high explosives that differs from primary explosives in their reduced sensitivity, making them suitable for use as the primary charge in various applications.
These explosives are intentionally designed to be less prone to accidental detonation and can withstand typical handling procedures.
Their inherent stability makes them pivotal for scenarios where safety considerations are paramount, notably in industries like mining, construction, and demolition.
Unlike primary explosives, secondary explosives exhibit a greater tolerance to external stimuli, contributing to their widespread use in controlled environments.
Their enhanced safety profile and reliability make them indispensable for applications requiring a balance between explosive power and a reduced risk of unintended ignition.
In essence, secondary explosives play a pivotal role in ensuring the efficiency and safety of various industrial activities where controlled detonation is essential.
